The heater tank contains no replaceable parts. The entire heater tank must be
replaced if service is required.
Be certain that the dispenser nozzle is snugly threaded onto the spigot assembly.
AUTHORIZED SERVICE PERSONNEL
CAUTION: Only trained and certified electrical, plumbing, and refrigeration technicians should service this unit. ALL WIRING AND PLUMBING MUST CONFORM TO NATIONAL AND LOCAL CODES.
HOT WATER WARNING
WARNING: This unit dispenses HOT water (160° F (71°C) - 205° F (96°C) during the rinse cycle.

CO2 (CARBON DIOXIDE) WARNING
WARNING: CO2 Displaces Oxygen. Strict Attention must be observed in the prev ent ion of CO2 gas leaks in the entire CO2 and system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience tremors which are followed rapidly by loss of consciousness and death.
CAUTION: PRECAUTIONS TO BE TAKEN IN STORAGE: Store and use with adequate ventilation. Firmly secure cylinders upright to keep from falling or being knocked over. Screw valve protection cap firmly in place by hand. Store only where temperature will not exceed 52°C (125°F). Store full and empty cylinders separately. Use a first-in, first-out inventory system to prevent storing full cylinders for long periods.
630460171 - 3 May 7, 2002
Lipton Brewed Iced Tea Training, Installation, & Service Manual
CAUTION: PRECAUTIONS TO BE TAKEN IN HANDLING: Protect cylinders from damage. Use a suitable hand truck to move cylinders; do not drag, roll, slide, or drop cylinders. Never attempt to lift a cylinder by its cap; the cap is intended solely to protect the valve. Never in sert an objec t (e.g. wrench, screwdriver, pry bar) into cap openings; doing so may damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. Open valve slowly. If valve is hard to open, discontinue use and contact your supplier. Never apply flame or localized heat directly to any part of the cylinder. High temperatures may damage the cylinder and could cause the pressure relief device to fail prematurely and venting the cylinder contents. Never strike an arc on a compressed gas cyl inder or make a cylinder part of an electrical circuit. For additional information on storage and handling, refer to Compressed Gas Association (CGA) pamphlet P-1, “Safe Handling of Compressed Gases in Contai ners,” available from the CGA.
Shipping And Storage
CAUTION: Before shipping, storing, or relocating the unit, product extract systems must be sanitized; completion requires purging all sanitizing solution from the systems. In addition, all liquids, after sanitizing, must be purged from the unit. A freezing ambient environment causes residual sanitizing solution or water remaining inside the unit to freeze resulting in damage to the internal components.
K
EY THINGS TO KNOW
Always unplug/disconnect the power to the dispenser before servicing.
Verify adequate water line pressures and volumes.
Verify water quality, optimum dispense taste may require water treatment.
Rinse water is very hot (160°- 205° F (71°- 82°C)).
630460171 - 4 May 7, 2002
Lipton Brewed Iced Tea Training, Installation, & Service Manual
Do not activate the heater until the water tank is full.
Rinse must be performed at least once every 24 hours or the brewer will lock out
and will not dispense product.
The heater tank contains no replaceable parts. The entire heater tank must be
replaced if service is required.
Warning Battery Life: Disconnecting the power supply or turning the power
switch off for longer than 48 hours will result in a service call to reprogram the dispenser. The battery will recharge itself when the power is restored to the board.
CLEANING AND SANITATION PRACTICES
It is imperative that the daily cleaning procedures, hot water flush, and monthly sanitizing procedures be followed as outlined in chapter 4.
WARNING: Failure to follow the scheduled cleaning and sanitizing procedures shown in chapter 4 may result in the growth of potentially harmful bacteria in the dispensed tea product.

SYSTEM OVERVIEW
The Lipton Iced Tea Brewer (LBIT) looks and operates like a leaf tea brewer. The LBIT instantaneously mixes and dispenses tea extract, hot water, cold water, and liquid sweet­ener to provide a finished tea product. Unlike leaf tea brewers, the LBIT does not have high maintenance and operational costs, and it is not as susceptible to the bacterial growth inherent to leaf tea brewers.
The following descriptions provide basic information of:
Theory of Operation
Function Keys
Menus and Modes of Operation
Capacities.
THEORY OF OPERATION
The fresh brewed process involves the mixing of concentrated (100:1) tea extract with hot water in order to brew the tea. A residence time of about 0.50 seconds ensures that the tea mixture is adequately dispersed and increases clarity.
A metered quantity of cold water is added to the brewed tea mixture to produce finished
tea. The cold water reduces the temperature of the final product to approximately 90° F (32° C). This temperature is similar to iced tea product dispensed from leaf tea brewers.
FUNCTION KEYS
The LBIT controller is a specific purpose circuit board residing within the brewer. The controller monitors inputs, controls outputs, and provides service and display functions.
Keys providing the basic operations within the controller are labeled Language (-), Menu (+), Stop (#), Rinse (<), and Run (>). The base operations of the keys are as follows.
Language key
Pressing this key will toggle the display between English and Spanish.
Menu key
Pressing this key will advance the display to the beginning of the next menu item. There are five menu functions that may be selected: Data View, Set - Time, Strength, Service, and Set-up.
Stop key
Pressing this key will put the brewer in stop mode. In this mode all normal functions occur except that tea will not be dispensed when the spigot handle is pulled.

Rinse key
WARNING: This unit dispenses HOT water (160° F. ­205° F. (71°C - 96°C) during the rinse cycle.
Pressing this key will place the brewer in the rinse cycle mode. In this mode the brewer will require user intervention to initiate each flush of hot water through the system. This is done by opening the spigot when prompted to do so on the display. After the rinse is completed, the brewer automatically returns to run mode.
Run key
Pressing this key will return the brewer to run mode. This is the only mode where a normal dispense is available.
NOTE: While in run mode, if an alarm occurs (over temp, sold out, etc.) the brewer will display the current er rors being de tected. Press­ing the LANGUAGE key will step through the current errors being de­tected.
MENUS AND MODES OF OPERATION
Pressing the MENU key will scroll through five basic modes in a round robin fashion. The menus and their order are: DATA VIEW, SET TIME, STRENGTH, SERVICE, and SET­UP.
To enter a selected mode, the STOP (#) key may be pressed. Once a particular mode is entered, the keypad keys are referenced as (-), (+), (#), (<), and (>). Display screen prompts will tell the operator what to do. In general the keys will have the following func­tion: Scroll forward or backward press (>) or (<), change a value press (+) or (-), to exit or enter a mode or sub-mode (#).
DATA VIEW mode
Scroll to the Data View Mode using the menu key. Press the (#) key to enter. Press the (>) to advance. The Data View sub modes include: Time of Day, Water Temperature, Gallons of tea poured in the last 30 days, Total Gallons of tea poured over the life of the brewer, Number of tea sold outs recorded (bags used), Number of sweetener sold outs recorded (bags used), and the Number of days the brewer has been in operation.
